### Name

FDC3 Payments Adaptor

### Slug

fdc3-payments-adaptor

### Business Problem & Solution

Currently, the FDC3 standard lacks a unified mechanism to seamlessly initiate institutional payments and bridge them into DLT/blockchain
settlement networks.

This software solves that by providing the reference implementation for the `InitiatePayment` intent and `fdc3.paymentContext` (currently
proposed for FDC3 3.0 in Discussion #2178 and PR #2204). It acts as a desktop agent bridge that allows traditional financial desktop
applications (e.g., Bloomberg, Symphony, OpenFin) to trigger standard FDC3 payment intents, automatically translating them into ISO 20022 `pacs.
008` Customer Credit Transfer XML, and dispatching them to Layer-1 DLT settlement networks.

### Mission Statement

The mission of the project is to provide a standard reference implementation and adapter bridging FDC3 institutional desktop environments with
blockchain and DLT settlement networks via ISO 20022 messaging.
